To all whom it may concern-:-

Be it known that I, Gnovnn PERRY, a citizen of the United States ofAmerica, and resident of Chicago, Cook county, Illinois, have inventedacertain new and useful Improvement in Book-Marking Devices, of whichthe following is a specification.

My invention relates to book marking devices, and more particularly todevices of the kind that have one or more marking members, each of whichhas an index projecting beyond the leaves, and all of which arecontrolled by a common element to hold them in place.

Among the objects of my invention are the following: To provide a deviceof the above character, the marking members of which are adapted each tobe removed without the necessity of disturbing the others, or ofremoving the common member; to provide a device by means of which it ispossible to turn quickly to any section of the book previously markedwithout having to handle the leaves, the markers of which will remainsecurely in place whether the book is closed or open and notwithstandingthe fact that the members are individually removable; to provide adevice which may be easily and quickly attached to and detached from abook without in any way marring the same; to provide a device of theabove character. which is automatically adjustable to books of differentsizes, the marking elements of which are light and thin and yet withsuflicient rigidity to enable them to be satisfactorily pressed intooperative position in engagement with the flexible common holdingmember; to provide marking devices having peculiarly and suitably shapedterminals for facilitating the operation of placing them in position andof removing them; and to pro vide details of improvement tending toincrease the efficiency and serviceability of a book marker of the abovecharacter. The means for accomplishing the foregoing are hereinafter setforth and claimed.

Referring to the accompanying drawing,

Figure 1 is a view of the book as it would appear when opened on atable, showing the book mark with a number of marking memhere inposition.

Fig. 2 is a view of the book on end giving a clearer view of the device.

Fig. 3 shows detail means for holding the common member in position.

Fig. a is an enlarged view of one of the marking members.

Referring more in detail to the drawings it will be seen that the markerA (Fig. l) is T shaped, and that on the end of the arm that extends tothe right there is a number 14 for identifying that particular marker.number maybe substituted by a letter or any other suitable character,and may be remov able or adapted to be erased. The other limb of themarker which is at right angles is provided at the lgwer terminal with aslanting point B, and a notch C. The upper end is provided with a pointD and a notch E having a wider trough than the notch G. Referring to theother figures there is shown a common element F, which may be made ofany suitable elastic material. This elastic element can be slipped overthe leaves of the book as clearly indicated, for example, in Fig. 2, andbecause of this elastic quality the book may be opened or closed withoutany difficulty and without any danger of the clastic coming 0H, sincewhen the book is open there is a tendency, as indicated in Fig. 1, ofthe elastic to crawl in the direction of the hinge of the book. Afterthe elastic is once in position, if it is desired to mark any particularpage, the marker 1 f (Fig. t) may be taken up and inserted in position,as shown in Fig. 1 with the notch C engaging the lower side of theelastic and the notch E engaging the upper part of the elastic. Thenotch C since it is V shaped in form, insures that the markers A are allheld in the same relative position nconstantly, that is, if the markerA, for example, is accidentally pulled either one way or the other, thetension of the elastic will always tend to pull the marker back intoposition.

Referring to the drawings it will be seen hat I provide a strip orstring K, linked with the band F, at the lower end of the book for thepurpose of raising the elastic to latch and unlatch the markers. Thisloop acts as a latch string, and may be slid along the band to any pointdesired. However, it will be understood that instead of the loop anordinary string tied to the band might also be used instead, if desired.I have designed the markers (Fig. l) with a sharp, upper end so that theupper end may be easily shoved into position under the band. The lowerend, however, I have made rather blunt in order that the lower end maynot This I be so easily inserted in place in this manner. .After'theupper end is latched into position the lower end is allowed to rest onthe band; then by pulling the latch string the band is drawn out andstretched over the blunt end and allowed to drop into the notch. Theobject in this arrangement is to avoid the necessity of using the markerto stretch the band, in order to shove the lower end under the band in amanner similar to the upper end. When this is done there is a tendencyto warp and distort the band, making it necessary to run the hand overthe marker and consequently over the page to straighten it out. Theobject, therefore, in making the lower'end blunt is to discourage thismethod of introducing the marker in place.

It will be seen that this elastic can be held in position if it shouldbe so desired by pro-- viding clips G, which project over the edges ofthe book a short distance. These clips 7 may be riveted or glued to thepage or fastened 1n any sultable manner, or the elastic might be held inplace by suitable straps H, which also may be secured to the book in asimilar suitable manner.

It will be seen, therefore, that I have de vised a highly improved bookmark which is compact and convenient, and which p0ssesses all of theadvantages already enumerated.

WhatI claim as my invention is:

1. In combination, a plurality of leaves, a flexible member embracingsaid leaves and a marker element, said marker provided with a taperingend for raising the flexible member whereby the marker may be insert-.

the flexible member whereby the marker may be inserted thereunder anddeposited between said leaves, each marker also provided with a notchbehind the tapering section for latching the marker in place under theflexible member whereby all the markers may be lined up.

3. In combination, a plurality of leaves, a flexible member embracingsaid leaves, a plurality of strip marker elements, each marker providedwith a tapering end for raising the flexible member whereby the markermay be inserted thereunder and deposited between said leaves, eachmarker also provided witha notch behind the tapering section forlatching the marker in place under the flexible member, whereby all themarkers may be lined up and each marker provided also with a notch nearthe other end whereby the marker may be latched at the other end by saidflexible member.

4-. In combination, a plurality of leaves, a flexible member embracingsaid leaves and a plurality of marker elements, each marker providedwith a tapering end for raising the flexible member whereby the markermay be inserted thereunder and deposited between said leaves, eachmarker also provided with a notch behind the tapering section forlatching the marker in place under the flexible member, whereby all themarkers may be lined up and a sliding latch left permanently loopedaround the flexible member for unlatching the marker elements.

5. A strip boolemarker to go between the leaves of a book, a notch nearthe end of the strip, said notch having a side at an angle to the lengthof the strip, a flexible member across the leaves near the binding foren-- gagement with said notch, said side acting as a stop for saidflexible member, a tapering point for said strip whereby the ends of thestrip having said notch may be inserted under the flexible member tolatch the strip in position, and a notch near the other end of the striphaving a side at an angle with the length of the strip, said flexiblemember extending across the other end of the book for engagement withsaid second notch, said side of said second notch acting as a step forsaid flexible member.

Signed by me at Chicago, Illinois, this 21st day of April, 1915.
